1. An image reading apparatus comprising:
a transparent member including a document placing surface on which a document is placed;
a document pressing member configured to press the document placed on the transparent member against the transparent member;
a hinge configured to support the document pressing member so as to be pivotable about a pivot shaft with respect to a casing of the image reading apparatus between a closed position where the document pressing member presses the document against the transparent member and an open position where the document pressing member permits removal of the document from the transparent member;
an image reading sensor configured to read an image on the document placed on the document placing surface;
a first abutment portion against which a front edge portion of the document placed on the document placing surface is abutted in order to position the document at a reference position for reading by the image reading sensor, the first abutment portion being provided at one portion of a front end on a side far from the hinge, among a pair of ends of the document placing surface in a front-rear direction orthogonal to the pivot shaft;
a second abutment portion against which a side edge portion of the document orthogonal to the front edge portion is abutted in order to position the document at the reference position, the second abutment portion being provided at one side with respect to the first abutment portion in a left-right direction orthogonal to the front-rear direction; and
an inclined surface provided at another portion of the front end and on a side opposite to the second abutment portion with respect to the first abutment portion in the left-right direction, and inclined upward toward the side far from the hinge.
